Subject: [patch net-next 07/16] mlxsw: spectrum_switchdev: Break mid deletion into two function

From: Nogah Frankel <nogahf@...lanox.com>

Break mid deletion into two function, so it will be possible in the future
to delete a mid entry for other reasons then switchdev command (like port
deletion).
